Though still without a launch program for its new 9,500- to 12,000-pound-thrust engine, Snecma has reported good progress in development work for its new Silvercrest powerplant series for large business jets and small regional airliners. As of
the end of January, the French manufacturer had completed 35 hours of combustion testing since starting work on this phase of the $100 million development on Nov. 30, 2007.

Among the turbine engine programs Honeywell is featuring at Booth No. 2137 this week are a completely factory-remanufactured version of the venerable T53 that powered the Huey series and the brand-new HTS900 turboshaft for the Army Bell ARH-70A armed reconnaissance helicopter.

Pratt & Whitney Canada’s helicopter turboshaft engine business has enjoyed
an unprecedented surge in recent years, thanks in part to the company’s development work on turbofan engines for business jets, company executives said.

Pratt & Whitney insists its geared turbofan (GTF) engine will have “fuel burn parity” with the competing open-rotor designs being studied by CFM International, Rolls-Royce and Snecma, all of whom have rejected geared fans as the way forward.

Honeywell Engines has adop-ted a pioneering role in the U.S. Army’s Small Heavy Fuel Engine (SHFE) development program, an advanced joint program started five years ago to develop and demonstrate turboshaft engines in the 700-shp class. The program has sought to achieve a number of lofty goals including a 20-percent reduction in specific fuel consumption, a 50-percent power-to-weight improvement and a 35-percent reduction of life-cycle costs.

CFM International has thrown down the gauntlet to engine manufacturers hoping to compete on the next generation of single-aisle airliners by accelerating its research on an advanced engine to replace its CFM56 by as early as 2015, the company announced here yesterday.

The efficiency of the gas turbine engines that power today’s commercial and military aircraft is approaching the highest level possible with current turbofans. But a totally new technology being pioneered by GE Aviation and researchers worldwide promises far simpler, more efficient engines that will extend aircraft range, cut fuel costs and reduce emissions.

When French President Nicholas Sarkozy made his first official visit to China last November he returned with the confirmation of orders for 110 Airbus 320s and 50 A330s. Safran, the French engine, equipment and systems group, stands to benefit from these deals, especially through the possible selection of its CFM56 engines by Chinese customers.

France-based engine manufacturer Snecma has reported “positive results” for the first 35 ground test hours of its Silvercrest core engine. In an unusual move, the company has begun the test program without announcing a launch application for the new turbofan, which is targeted for applications on future super-midsize to large business jets. The core engine achieved “all the expected performance objectives” for these combustion trials.
